Hi, I'm Ahmed 👋

💡 Data Analyst & Builder of Practical Tools
I enjoy turning messy data into clear, simple insight and building small, useful apps that save people time.
My background combines banking & fintech analytics, data science, and hands-on software projects in Python and Android.

🔭 Current Focus

  • 📊 Data Analytics & BI – Python, SQL, Power BI, and real-world datasets
  • 🤖 Machine Learning for Customer Behaviour – churn, segmentation, forecasting
  • 🧰 Productivity Tools – desktop apps like Text File Searcher, file comparators, and PDF utilities
  • 📱 Android Apps – Kotlin apps like ScholarBio and a crossword puzzle game

🛠️ Skills & Tools

Languages & Scripting

  • Python, SQL, Kotlin, Java (basics), Bash (basics)
  • ML/AI: Scikit-learn, TensorFlow basics, Pandas, NumPy , Matplotlib
  • Other Tools: Git, GitHub, Jupyter Notebook , pycharm, Microsoft SQL, NoSQL (Mongo DB)

Data & Machine Learning

  • pandas, NumPy, scikit-learn
  • Data cleaning and feature engineering
  • Classification, regression, customer churn models
  • Visualisation with Matplotlib / Power BI

Analytics, Reporting & Databases

  • Power BI, Excel (advanced), CSV/Excel data preparation
  • Relational databases and querying with SQL

Software & App Development

  • Python desktop apps with Tkinter
  • Android apps with Kotlin, Retrofit, Room, Hilt, Coil
  • Basic Git/GitHub workflow (branches, commits, pull requests)
  • Packaging Python apps with PyInstaller (.exe)

Tools I Use Often

  • VS Code, PyCharm
  • Jupyter Notebook
  • Android Studio

🚀 Selected Projects

  • 🧭 Text File Searcher – Search across .txt files with a simple Tkinter GUI
  • 🧾 DataPrep-Pro – Clean, prepare, and explore datasets faster
  • 🧱 TextFileCompareApp – Compare contents of two text files side by side
  • 📄 HexaPDF Editor – Lightweight PDF editing/annotation tool
  • 🎓 ScholarBio (Android) – Kotlin app with modern Android stack
  • 🧩 Crossword Game (Android) – 1000-word, 100-level crossword with themes and progress tracking

Many of these are available in my repos here on GitHub.

🌱 What drives me

I like building things that are actually used – tools that make data work easier for analysts, students, and developers.
I’m especially interested in:

  • Using ML to understand customer behaviour and reduce churn
  • Turning raw transactional data into clear, decision-ready insight
  • Sharing my work openly so others can learn from real-world projects

I learn and build continuously, and I’m slowly shaping this profile into a portfolio for data, ML, and fintech-related work.
